ROTATING TABLE.

Application filed May 6,

T 0 all whom it may concern Be it known that I, Tnnnn'r n DAVIDENIA, a citizen of Russia, residing at Toronto, Canada, have invented certain new and useful Improvements in Rotating Tables, of which the following is a specification.

T his invention relates to improvements in tables particularly tables for self-service, and it is the principal object of the invention to provide a table of this character which allows a diner to bring within his reach any dish on the serving table without the necessity of getting up from his seat and without disturbing his co-diners or needing the assistance of an attendant.

A further object of the invention is the provision of a table of this class which allows a convenient step by step operation of the auxiliary or serving table from the seat of a diner and produces an automatic stop of said auxiliary table after each operation.

These and other objects and advantages of my invention will become apparent as the description proceeds and will then be specifically pointed out in the appended claims.

In the accompanying drawings Figure 1 is a top plan view of a table constructed according to the present invention.

Figure 2 is a side view thereof.

Figure 3 is a top plan view of the table after the removal of its top plate.

Figure 4: is a Vertical section through a table constructed according to the present invention.

Figure 5 is a detail view of an operating disc and its cooperating parts.

The table comprises the top plate 10, a box 11 on the underside of the plate and the support or post 12 resting on a pedestal 13 supported by casters 14:.

The top plate 10 is stationary with the exception of its center part 15 which is rotatable within a circular opening of the plate 10 and adapted to carry a plurality of dishes 16 for bread, butter, etc.

The number of seats provided at the table is indicated by a plurality of large dishes 17 and smaller dishes 18.

lVithin the box 11 underneath the rotatable part 15 and the plate 10 the mechanism for rotating the center part 15 is located. This mechanism comprises a disc 19 rotatably mounted on a board 20 of the box 11. To the upper face of this disc are se- 1921. Serial No. 467,344.

cured the ends of the shorter arms of angular levers 21, the outer ends of which are held 1n eyes 22 of the table plate and project therefrom so as to allow. a diner to exert a pull on their ends.

To the periphery of the disc 19 the end of a strap 23 is secured, the inner end of .WlllCll engages a ring 29 fixedly secured within the box 11. l

The end 27 of a pin 25 pressed outwardly by a spring 26, is secured to strap 23 intermedlate its ends and said strap is guided around ring 29 and secured to the same at its end as indicated at 28 (Fig. 3). Secured to plate 15 is a shaft 30 to which casing 29 is secured.

The bevel gear 32 is loose on shaft 30. Wlthin the casing 29 is a spiral spring 31 the inner end of which is secured to bevel gear 32 and the other end to casing 29.

Stop pins 33 are secured to the outer peripheral wall of casing 29 adapted to successively engage the pin 25.

The bevel gear 32 is in mesh with a similar bevel gear 34 secured within the post 12 by the side of the shaft 30 on a transverse rod The shaft of the bevel gear 34.- has a key hole 36 for engagement of a suitable tool for operating the gear to wind the spring, and a pawl 37 is provided for preventlng a sudden unwinding of said spring.

The device operates as follows If for instance a person takes a seat at the table in front of a plate for instance 38' and desires to supply himself with bread on dish 39, he will exert a pull on the end of lever 21 in front of him which will rotate the disc 19 to operate cable which is secured with one end to ring 29 and the end 27 of pin 25 to which said cable is secured will operate stop pin and release the engagement between stops 25 and 33 so that the plate 15 and the dishes will rotate under the action of the spring 31 for one sixth of the full revolution. This operation will have to be repeated until the bread dish will arrive in front of the diner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. In a table of the class described a top plate having a circular central opening, a post, a vertical shaft in said post, an auxiliary table upon the upper end of said shaft to rotate in said opening of the top plate, a disc underneath said top plate, a.

box secured to the under face of said top plate, a plurality of angular arms secured with one of their arms to said disc and with their other ends projecting from said box in front of each seat at the table, a strap secured with one end to the periphery of said disc, a ring fixedly secured Within said box to which the other end of said strap is attached, a spring controlled stop on said strap, means for normally holding said auxiliary table in i'ts'positi'on of rest, and means for releasing said stop for allowing a step by step rotary motion of said. auxiliary table upon the operation of said arms.

2. In a table of the character described comprising a top plate having a central. circular opening, a post, a vertical shaft in said post, a disc under said top plate, an auxiliary table revolving with said shaft within the circular opening of said top plate. a box under the top plate, a plurality of angular arms secured with one end'to the upper face of said disc, the other ends of these arms projecting from said box in front of each seat at the table adapted to be operated for imparting to said disc a step by step rotary motion, a strap secured to the periphery of said disc, a ring on said auxiliary table to which the free end of said strap is attached, a spring controlled stop pin secured to said strap, a casing within said box, a spring in said casing, a bevel gear loose on said shaft outside of said casing, one end of said spring secured to said casing and the inner end to said bevel gear, stops on theouter Wall of said casing adapted to be normally engaged by said stop pin,

and a key operated. bevel gear in mesh with said first named gear for allowing; a winding of said spring upon its operation by a key.

In testimony whereof I have affixed my signature.
